Revelation 12:8

Prevailed not. Inasmuch as the phrase “war in heaven” (v. 7) may have a dual application, describing both the original controversy in heaven between Lucifer and God and the controversy on earth between Satan and the incarnate Christ, the phrase “prevailed not” would appropriately apply to both stages of the conflict. In neither was Satan successful.

Their place. This phrase may be understood either as the place once possessed, or occupied, by them, or the place once assigned them. Lucifer was at one time the covering cherub (see on Eze. 28:14), and the angels who joined him in rebellion held various positions of responsibility. These, Lucifer and his angels lost when they were cast out of heaven.
